I applied through university. The process took 2 weeks. I interviewed at Rocket Lab
Interview
My interviewer told me about herself and then asked me about project that I had worked on that I listed in my resume. She expected very in depth responses, but all in all, I thought it was a fair interview. The hiring managers are very experienced and accomplished aerospace engineers boasting accomplishments like being manufacturing team leads at SpaceX for 5-6 years, so make sure you're ready to talk in depth about your experiences.
Interview questions [1]
Question 1
What was one thing you received feedback on while co-oping at Gulfstream Aerospace?
Complex. Slow. Scary. I dont know why they had to make it a difficult and uncertian process for all the people who were involved. But that seems to be the way they like to do it.
